Manchester United are monitoring Wesley Sneijder's situation ahead of the January transfer window, ESPN has been told, as it emerged on Friday that Inter will consider selling the Dutch playmaker after contract negotiations stalled.

The Old Trafford club came extremely close to signing Sneijder in August 2011 only for the deal to fall down over financial demands. But with United's hand now strengthened due to the player's current difficulties, ESPN understands they are strongly considering another bid with Nani possibly going the other way.

United manager Sir Alex Ferguson's relationship with the Portuguese winger has worsened significantly over the past year and the club even looked to try and sell him in the summer. Even if Sneijder does not arrive at Old Trafford, Nani - who is currently injured and could be out until the New Year - may yet move to either Inter or Juventus.

United have also been heavily scouting PSV Eindhoven's highly-rated Kevin Strootman and are one of a number of clubs watching Crystal Palace's Wilfried Zaha, although Arsenal are understood to be favourites if the young forward were to leave Selhurst Park.

In Italy, meanwhile, Sneijder looks set to be again left out of the team for Inter's match with Palermo on Sunday.

"Sneijder isn't playing because the coach doesn't think he's at his best, above all psychologically," club president Massimo Moratti said.

"For us it's natural to look for a way to not be forced to sell him and he has the right to not accept our offer. If it stays like, the solution will be on the transfer market."

After enduring a tricky start to his Manchester United career, perhaps it is fair that Marcos Rojo celebrated so boisterously as he watched his first professional club Estudiantes beat fierce rivals Gimnasia
